To all whom may conceive: i

Be it known that Laoo Lisse, e citizen of the United States oit .eimer-ice, end resident of Bellevue, county et' ESaiiiploell, Stute of Kentucky, have invented certain new end useful improvements in lnstanleeneous VVeter-l-leeters, of which the follow? This invention relates to Water heaters, end particularly to instantaneous Water heaters, and means for controlling tliedeliv` ery of Water and gas to the heaters. Y

An object of this invention'is to produce e. Water heater in Whichnew and improved means are employed for heating the Water passing through the'heater coils.

A further object is toproduce e heater provided with u, number of separetecoils,

` each of'whiohI is'piovded withy ey seperate burner, so that the heeteii is more eitective and economical than ordinary heaters.

A further object is to produce e heater iii which improved means are employed tor controlliiig the delivery of Water und ges to the lfleat'. i

furt'her object is toproduce Ineens for vcontrolling the supply ofpges to the burners of the heater, which will not deliver gas ex'- cept when Water is delivered to the coils of the heater.

A further -object is to produce Wai-ter and ges delivery valves, which are so constructed that uo stuffing looxes ere necessary.

These and other objects l attain in enA up pmatus embodying the features hereiny ,de`- scribed and illustrated.

In the drawings for this application and forming a part thereof, Figure 1 is e pei*- spective view of e heater embodying my invention, e portion of the inelosed easing being broken away for convenience of illustretion. Fig. 2 is a sectional elevation of e water supply valve and a: gassupply valve, in connection with al manually operated controlling inealis for the valvesJ lfigv 3 is a perspective View of aburner, which forms e detail of my invention: Fig, l is 'e perspective view of e coil-support piece, which ,tney be formed integrally with the burne'i?. Fig. 5 is e' perspective view of apilot buener, which is employed with the appaifetus illusA trated; Fig: 6 is a sectional view' along the line 6-6 of Fig. 2, and. illustrates'the construction oi Vthe Weten supipl valve'.

The apparatus illustre/ted es embodying my invention consists of three separa-te heater coilsy 8, 9 and l0, throughl which the Water to loe heated successively iovvs,l e sep irate ges burner 1-1 i'or each coil, e menuelly controlled' supply valve' 112, which is actuated-'by Water pressure, 'ande gessup'ly velvel, the operation of yWlii'oliy is controlled by the Water supply velfve.A

l Esch heater coil consists oiftvvo layers of horizontally disposed turns, soarranged that the Water to beheated enters the outer turn' of? the' lower layerg; end is delivered roeithe-oueer turnjof theupper layer.

Each buzner communicates `with the delivezfy port 29 oit tlaeges valve 13 through its communicating pipe 1-6 and' a supply ie 19, and is loca-ted directly under one of t heater coils.4 The burners ere supported ley the communicating piping. and in turn support the coils. le coil-support piece 21 is formed integrally with each burner ll, end is provided vvitle1 e vertically proiecting eilt tension 22 which projects up 'through the tusns of the ecljeoent coil. This arrange'- ment supports and holds the coils firmly in placez i I A. pilot burner 2' isprovided for the 4lie-eter end consists of three branches, eelcli o Whichextends into'closeprosimity with one of the burners ll and is adapted to light the bur-'nee when yvel-ve 22 is opened.
